As best illustrated in FIGS. 1 through 6, the chain saw guide barmounting device 10 generally comprises a first plate 12 that isconfigured to mount to a support structure, such as a table. In oneembodiment, the first plate 12 is rectangularly shaped.

A second plate 14 is coupled to and extends perpendicularly from thefirst plate 12. The second plate 14 extends longitudinally along thefirst plate 12 from proximate to a first end 16 of the first plate 12toward a second end 18 of the first plate 12.

In one embodiment, the second plate 14 comprises a pair of first panels20. Each first panel 20 is coupled to and extends perpendicularly fromthe first plate 12 to define opposing ends 22 of the second plate 14. Inanother embodiment, the second plate 14 comprises a second panel 24 thatis coupled to and extends between the pair of first panels 20. In yetanother embodiment, the second plate 14 comprises a third panel 26. Thethird panel 26 is positioned substantially equally distant from the pairof first panels 20.

In one embodiment, the device 10 comprises a set of third plates 28. Thethird plates 28 are coupled singly to the pair of first panels 20 andthe third panel 26. The third plates 28 are coupled to the first plate12. The third plates 28 are positioned to stabilize the pair of firstpanels 20 and the third panel 26 relative to the first plate 12. Inanother embodiment, a lip 30 is coupled to and extends perpendicularlyfrom the second panel 24. The lip 30 is opposingly positioned relativeto the third plates 28.

Each of a pair of couplers 32 is coupled to and extends perpendicularlyfrom the second plate 14. Each coupler 32 is complementary to arespective penetration that is positioned in a guide bar of a chain sawassembly. The couplers 32 are configured to couple to the penetrationsin the guide bar to couple the guide bar to the second plate 14. Theguide bar is positioned substantially perpendicularly to the first plate12.

In one embodiment, the couplers 32 are positioned singly on the pair offirst panels 20. In another embodiment, each coupler 32 comprises a bolt34, a first tube 36, and a first nut 38. The first tube 36 is positionedaround the bolt 34 such that a threaded section 40 of the bolt 34 ispositioned distal from the first panel 20. The first nut 38 isreversibly couplable to the threaded section 40. The first tube 36 isconfigured to abut the guide bar to separate the guide bar from thefirst panel 20. The first nut 38 is positioned to couple to the threadedsection 40 of the bolt 34 to couple the guide bar to the first panel 20.

A second tube 42 is coupled to and extends perpendicularly from thethird panel 26. The second tube 42 is configured to abut and stabilizethe guide bar that is coupled to the first panels 20.

A bracket 44 is slidably coupled to and extends perpendicularly from thefirst plate 12. The bracket 44 is positioned between the second plate 14and the second end 18 of the first plate 12. In one embodiment, thebracket 44 is L-shaped when viewed longitudinally.

In another embodiment, a fourth tube 46 is positioned between thebracket 44 and the first plate 12. The fourth tube 46 is fixedly coupledto the first plate 12. Each of a pair of first rods 48 is coupled to andextends from the fourth tube 46. The first rods 48 are threaded. Each ofa pair of second nuts 50 is complementary to the first rods 48 such thateach second nut 50 is reversibly couplable to a respective first rod 48.A slit 52 is positioned longitudinally in the bracket 44. The slit 52 ispositioned to insert the first rods 48. The bracket 44 is variablypositionable relative to the second plate 14 and the second end 18 ofthe first plate 12. The first rods 48 are positioned to couple to thesecond nuts 50 to selectively couple the bracket 44 to the fourth tube46.

A second rod 54 is selectively couplable to the bracket 44. The secondrod 54 extends perpendicularly the bracket 44. The second rod 54 isvariably horizontally positionable relative to the pair of couplers 32.A hub 58 is axially positioned on the second rod 54. The hub 58 isrotationally coupled to the second rod 54. The hub 58 is positioned torotationally couple to a cutting chain that is positioned on the guidebar. The cutting chain is positioned for maintenance, such assharpening.

A third tube 60 is positioned around the second rod 54. The third tube60 is positioned between the bracket 44 and the hub 58. The third tube60 is positioned to separate the cutting chain from the bracket 44.

In one embodiment, the second rod 54 is threaded. A third nut 56, whichis complementary to the second rod 54, is reversibly couplable to thesecond rod 54. A plurality of holes 62 is positioned in the bracket 44.The holes 62 are complementary to the second rod 54. The holes 62 arepositioned in the bracket 44 such that each hole 62 is positioned toselectively insert the second rod 54. The second rod 54 is positioned toreversibly couple to the third nut 56 to couple the second rod 54 to thebracket 44. The second rod 54 is variably horizontally positionablerelative to the pair of couplers 32.

In use, the first tubes 36 are configured to abut the guide bar toseparate the guide bar from the first panels 20. The first nuts 38 arepositioned to couple to the threaded sections 40 of the bolts 34 tocouple the guide bar to the first panels 20. The second tube 42, whichis coupled to the third panel 26, is configured to abut and stabilizethe guide bar that is coupled to the first panels 20. The slit 52 thatis positioned in the bracket 44 is positioned to insert the first rods48. The bracket 44 is variably positionable relative to the second plate14 and the second end 18 of the first plate 12. The first rods 48 arepositioned to couple to the second nuts 50 to selectively couple thebracket 44 to the fourth tube 46. The holes 62 are positioned in thebracket 44 such that each hole 62 is positioned to selectively insertthe second rod 54. The second rod 54 is positioned to reversibly coupleto the third nut 56 to couple the second rod 54 to the bracket 44. Thesecond rod 54 is variably horizontally positionable relative to the pairof couplers 32. The third tube 60, which is positioned on the second rod54, is positioned to separate the cutting chain from the bracket 44. Thehub 58, which is positioned on the second rod 54, is positioned torotationally couple to the cutting chain that is positioned on the guidebar. The cutting chain is positioned for maintenance, such assharpening.

With respect to the above description then, it is to be realized thatthe optimum dimensional relationships for the parts of an embodimentenabled by the disclosure, to include variations in size, materials,shape, form, function and manner of operation, assembly and use, aredeemed readily apparent and obvious to one skilled in the art, and allequivalent relationships to those illustrated in the drawings anddescribed in the specification are intended to be encompassed by anembodiment of the disclosure.

Therefore, the foregoing is considered as illustrative only of theprinciples of the disclosure.
